APPARATUS FOR HEATING WATER IN BATHS.

SPECIFICATION forming part of Letters Patent No. 433,490, dated August 5, 1890.

" Application filed September 21, 1889, Serial No. 324,636- (No model.)

To all whom it may concern:

Be it known that 1, JAMES REILLY, a citizen of the United States, and a resident of' Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Apparatus for Heating Water in Baths, of which the following is a specification.

The invention relates to improvements in apparatus for heating water in baths and other vessels; and it consists in a water jacket or casing communicating at its opposite ends with the bath and inclosing steam inlet and return pipes, the object being to establish a circulation of the water from the bath through said casing until the action of the steam shall have imparted the desired temperature thereto, after which the steam may be turned off.

The means for carrying the invention into effect are fully described hereinafter, and are illustrated in the accompanying drawings, in which- Figure l is a side elevation of a bath-tub with my invention applied thereto; Fig. 2, a top view, partly in section, of the tub, the apparatus constituting the invention being in section on the dotted line 2 2 of Fig. 1; and Fig. 3, an enlarged vertical section on the dotted line 3 3 of Fig. 2, showing the invention in cross-section with the means -of attaching it to the tub.

In the drawings, A designates the bath-tub; B, the Water casing; C, the inletpipe for steam, and D the return steam-pipe. The casing B is provided in its side and adjacent to its ends with the openings E F, the flanges G, surrounding said openings, being preferably brazed to the internally and externally threaded sleeves H, carrying the threaded nuts I on their exterior and receiving the ferrules J, through which the water from the tub circulates into and from the casing B. The side of the tub A contains apertures a a, through which the ferrules J are passed from the inner side of the tub when it is clesired to screw them into the sleeves H, and the outer ends of said ferrules are provided with flanges K, which have a bearin g against the inner surface of the tub. Between the nuts I and the outer surface of the tub are provided flexible washers L for insuring the formation of a tight joint around the aper tures a a.

The casing B is arranged at an oblique aning being preferably brazed to the exterior surface of the intermediate or return pipe D, as shown in Fig. 2, which projects outward beyond said end of said casing and is closed at its ends, the steam being permitted to escape therefrom through the discharge-pipe N. The outer end of the return-pipe D for steam is brazed to the coupling P, which at its outer end will be connected with a suitable source of steam-supply, and at its inner end is in direct communication with the interior steam -pipe 0, which is within and smaller in diameter than the return pipe D. The inner end of the steam-pipe C is open and delivers the steam into the inner end of the pipe D, whence the steam returns along the outer sides of the pipe 0 and escapes through the pipe N. The steam-pipes are support-ed at their inner. ends by means of steadying-pins Q, Which maintain the relative positions of said tubes.

In the use of the invention the live steam from some suitable source is admitted to the pipe C, while the water from the tub fills the casing B around the pipe D. The steam passes down the pipe 0 and returns on the outer side of said pipe and within the pipe D to the escape-pipe N, the effect being that the pipe D, becoming heated, imparts heat to the water in the casing 13, and the water becoming heatedcreates a circulation in the bath toward and from the heating devices. -After the water has acquired the desired temperature the steam may be cut off from the pipe 0.

I recommend the use of thin copper for the manufacture of the steam-pipes and watercasing hereinbefore described.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The bathtub and the elongated cylindrical water-casing B, secured to the side of said tub and communicating therewith the entire length of the interior of said wa-v through the openings E F, located adjacent to the ends of said casing, and apertures a a in the side of the tub, combined with means, substantially as described, for securing the casing B to the tub, the steam-inlet pipe D, having the coupling at its outer end and bein g open at itsinner end and extending nearly 2- The bath-tub and the Water-casing B in close relation to the side thereof and having flanged openings E F adjacent to its ends, the sleeves H and flanged ferrules J connecting said casing through its said openings with the interior of the tub, combined with the steam-inlet pipe 0, having the coupling at its outer end and being open at its inner end, the steam-return pipe D, inolosing said inletpipe and being within the water-casing B,

and the discharge-pipe. N, connected with said return-pipe, said inlet and return pipes extending nearly the entire length of said Water-casing, substantially as and for the purposes set forth.

Signed at New York, in the county of New I York and State of New York, this 19th day of September, A. D. 1889.

JAMES REILLY.
